PO\VDER-BIS?ENS`ENG BOX.

Application filed October i,

To @ZZ w hom t 'may conce/rn Be it known that HARRY L. DUNNn'r'r, a citizen of the United States, residing at Kansas City, in the county of Jackson and vState of Missouri, have invented certain new and useful improvements in Powder- Dispensing Boxes; and do declare the rollowing to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same, reference being had to 'the accompanying drawings, and to the letters and figures of reference marked thereon, which i'orin a part orl this specilication.

T his invention relates to powder dispensing \oxes, the main object being to provide x adapted to contain insect powder, the

a bo box being` in the orm or a bellows with a discharge opening through which the powder may be blown when it is desired to apply it.

The invention further contemplates a novel construction of dispensing carton or box which may be conveniently constructed, which will be efficient in practice and which will be inexpensive to make;

The novel features or' my invention willb be better understood by reference to the accompanying drawings, in which Figure l is a perspective view of a dispensing container constructed in accordance with my invention, parts being broken away to show the interior construction thereof.

Fig. 2 is a vertical, longitudinal, sectional view through the saine, and

Fig. 3 is an end view of the bellows spring and its end anchors.

The container proper may consist of an ordinary carton or box l, formed from a single blank in any well known manner. One end, for example 2, is provided with a discharge opening 3, originally covered by a wrapper l for the box l is generally covered by a label. The wrapper is sulicien't to prevent the accidental spilling of the contents or the box during transportation Specification of Letters Patent.

and upon the shelf orn the merchant. In orderto render the discharge opening 3 enective, it will be only necessary to punch the wrapper at the point 3 to complete the opening whereupon the contents maybe discharged.

I have provided an ellicient means for rendering the flexible top and bottom portions el and 5 effective as bellows to cause an ejection oit' the insecticide or other powder within the receptacle. The novel means for converting the box into a bellows is best shown in Fig. 3 as consisting of an upper anchor member G and Ia lower anchor member '7, the respective anchor members being preferably (zo-extensive with the top and bottom of the box and they preferably lie in close proximity thereto with an expansion spring 8 interposed between them. The ends or the expansion spring 8 are adapted to engage strips or securing members 9 and 10 cut from the body portions of the anchor members 6 and 7 by longitudinally slitting them so that the strips may be pulled away from the main body portion of their respective members 6 or 7 and allow engaging spaces for the ends 1l and 12 of the spring 8, the ends of the coil being adapted to engage between the strips 9 and l0 and the portions 6 and 7 as shown. The bellows attachment is then placed withinthe blank, which is then folded and pasted so that the parts will have the position shown in Figs. l and 2.

lf the opening 3 is uncovered and the operator grasps the top and bottom of the box between the thumb and ngers and presses after a manner common to a bellows operation, the exhausted air will force the powder in the container through the opening 3. When the pressure is relieved, additional air will pass into the box through the opening 3, ready to be expanded by the next compression to carry with it the powder, as will be well understood.

From the foregoing it will be seen that the device is easily constructed, simple in operation, inexpensive to make and that it will eiciently perform the function for which it is intended.

What I claim and desire to secure by Letters-Patent is:

1. A dispensing boi; for powders coinprising an inelosing casing having flexible Walls and a discharge opening, a coil spring within the casing, and anchors for the ends o the spring Comprising blocks having outstanding strips engaging the endsY of the i0 coil spring.

2. A dispensing box for powder comprising an inclosing easing, anchor members Within the rectangular easing' having nterinediate strip portions eut therefrom, and 1 5
